Cross gdb and threads

[Robert Trask]

I've recently tried to build a cross debugger  for a mips-linux target. For ordinary programs everything seems to work well. When we debug threaded programs gdb performs poorly.

When we set a breakpont anywhere but in the "main" thread (the one from which we launch the others) the debugger gets confused: no valid stack frame, can't resolve symbols, etc.

 

Here's my config entry:

 

../configure --target=mips-linux --prefix=/projects/san_engineering/tools --with-solib-absolute-prefix=/projects/bbp_ext16/systems/sbtools/x86-linux-rh6.0/mips-linux-2.7.16/mips-linux/lib

 

Does anyone have any insights into what is going wrong? Any patches or work-arounds I could apply?

 

(Or, hopefully, just another config itme?)

 

thx,
